a mechanism of identity creation which Hans-Georg Moeller and Paul D’Ambrosio in You and Your Profile, have termed profilicity, is closer related to sincerity than authenticity. profilicity is other-directed and reliant on the reactions of an audience. With sincerity, one’s family and community are the audiences that cast judgment on how sincerely, or properly, one plays the pre-determined roles.
Online social media being the audience instead of family and local community causes people to be less authentic and more conforming to online profile expectations. temptation is to do what gets likes, subscribers, and followers.

Authenticity is not other-directed because your mirror is the audience. self-creation is independent of pressure to get likes and subscribers and followers. The more humble self-creation is creating the authentic self. Lead me not into temptation.

sincerity is not as authentic because the audience is others and unknowingly we all wish to conform and be accepted so we adapt to what is expected. Success at being sincere builds EGO and shrinks humility for it comes with the praise of the audience.

To profile someone is to show a person a complete side view of your naked body sometimes hiding the front and back of your body with a towel.

An affliction or disorder of the outline or contour of the human face, especially when viewed from the side, that impairs another's judgement of the afflicted's relative attractiveness. Those who suffer from profilism are often attractive when viewed from the front.
